BERLIN (AP) — Production at Tesla’s electric vehicle plant in Germany came to a standstill and workers were evacuated after a power outage that officials suspect was caused by arson. The interior ministry in the state of Brandenburg says unidentified people are suspected of deliberately setting fire to a high-voltage transmission line on a power pylon. Police say they are examining a “letter of confession” by a leftist group in connection with the outage. Environmental activists have been protesting in a nearby forest against plans by Tesla to expand. Tesla CEO Elon Musk and Germany’s interior minister condemned the incident.
